Development And Teaching Practice Of App Inventor Programming Resources In Primary School Supported By Wechat Applet

With the rapid development of mobile Internet and artificial intelligence,programming education has entered the classrooms of primary and secondary schools and been rapidly popularized.The use of graphic programming tools in primary school can not only cultivate students’ programming ideas,but also their computational thinking.However,through the analysis of the current teaching status of programming in primary schools,it can be seen that the traditional teaching method cannot effectively cultivate students’ thinking ability.In this study,App Inventor was used as a primary school programming tool to develop the resources of micro-lecture based on the cultivation of computational thinking;before class,students can make full use of their spare time to learn programming;in class,students can discuss and share learning experience,teachers also have more time to guide students to conduct independent inquiry and actively seek solutions to problems.The research content of this article mainly has the following four parts:(1)This study takes senior elementary school students as the research object,studies the existing App Inventor textbook resources and other relevant literature,and analyzes the characteristics of elementary school senior students,so as to determine the App Inventor case content suitable for primary school calculation thinking cultivation.(2)According to the development process of micro-lecture,the five thinking dimensions of computational thinking(algorithm thinking,evaluation thinking,decomposition thinking,abstract thinking and generalization thinking)are integrated into each link of problem solving to develop resources.(3)Build WeChat applet that can meet the basic learning needs of students,and provide students with offline mobile learning tools for students to learn before class and consolidate after class.(4)Construct a teaching model suitable for this research,and apply the designed teaching resources to actual teaching under the guidance of the teaching model;Before and after the teaching,the students were surveyed with questionnaires to understand their level of computational thinking ability,interest in learning programming and learning attitude;Finally,analyzed and summarized the collected questionnaires,student works and learning data on the micro platform.The results show that the App Inventor primary school programming resource designed in this paper based on WeChat applets has a certain effect on cultivating students’ computational thinking ability,and has positive impact on students’ learning interest and learning attitude,which verifies the feasibility of this study.
